I'm only providing the flags for GCC builds.  I'm not willing to assume 
that non-GCC compilers take GCC flags.  If people have non-GCC, non-MSVC 
compilers, they can inform us, and we can add more flags.  I might also 
set up an area at the top of CMakeLists.txt that's meant for people to 
add flags we don't know about.
    

Fair enough.

  

I found that -fomit-frame-pointer causes chicken-boot to crash when 
compiled with MinGW 3.4.5.  So, I've turned it off for all MinGW 
compilers.  No idea if it affects anything other than 3.4.5.  You can 
see that there are testing issues.  Cygwin built fine without 
complaint.  Didn't actually test the end product though, as I relish the 
chance to blow up John Cowan's machine.  :-)  
    

Ooops!  VERY BAD PROBLEM.

When built under CMake (but not when built under autotools), the
chicken-setup.c file produces compiler errors from gcc.  I'm using the
autotools build for the present.
  

I take it you mean you're building on Cygwin?  I can't duplicate this.  Here's my full GCC command:

and here's my GCC version banner.  What's yours?

Diffing the two versions of chicken-setup.c show
only two presumably trivial differences: some comments refer to
/opt/chicken/darcs/chicken-setup.scm instead of just chicken-setup.scm,
and the ptable declaration at line 22369 contains strings of
the form "f_nnnn/opt/chicken/darcs/chicken-setup.scm" instead of
"f_nnnnchicken-setup.scm".

I've attached the chicken-config.h and chicken-defaults.h files
from the CMake build.
